... In the first 20 minutes, Sheila fills the pool at a rate of 20 L/min and thus adds 20 × 20 = 400 L of water to the pool. At this time, the pool needs 4000 − 400 = 3600 L of water to be full. After filling for 20 minutes, water begins to leak out of the pool at a rate of 2 L/min. Since water is still ...

... As you can see, the exponent of 10 is the number of places the decimal point must be shifted to give the number in long form. A positive exponent shows that the decimal point is shifted that number of places to the right. A negative exponent shows that the decimal point is shifted that number of pla ...

Elementary arithmetic
Elementary arithmetic is the simplified portion of arithmetic that includes the operations of addition, subtraction, multiplication, and division. It should not be confused with elementary function arithmetic.Elementary arithmetic starts with the natural numbers and the written symbols (digits) that represent them. The process for combining a pair of these numbers with the four basic operations traditionally relies on memorized results for small values of numbers, including the contents of a multiplication table to assist with multiplication and division.Elementary arithmetic also includes fractions and negative numbers, which can be represented on a number line.
